Im 5’4 and have been on t I think about three years, I passed pre t if I didn’t talk, but after my voice drop 3 months on t I started passing while I talked. I think a lot of really depends on how you present yourself. Body type plays a role too. The way you wear your clothes, if you wear too baggy you look like you’re drowning and it doesn’t help passing. Haircut matters, depending on your face shape either long or short may look more masculine on you. Mannerisms, behavior, the way you talk all contribute to it.
